LOOM-SH UTTLE.

SPECIFICATION forming part of Letters Patent No. 267,628, dated November 14, 1882,

Application filed January 4, 1882. (No model.)

i following is a specification, reference being had therein to the accompanying drawings.

My invention relates to loom-shuttles and it consists in the construction and arrangementot' its several parts, as will be hereinafter fully set forth.

In the drawings, Figure l is atop or plan view of a loom-shuttle; Fig. 2, a longitudinal section thereof; and Fig. 3a top or plan view of the end containingthetension-regulatingmechanism.

A is the shuttle-body. It is provided Withthe usual central recess, as shown.

B isthe spindle. It extends into the recess, andis pivoted at its shank or base end in a groove in the shuttle-frame. It is held in position by the pressure of the spring 11 upon the top of its shank, as shown in Figs. 1 and 2.

(J is the bobbin. It is placed upon the spindle B, and is held thereon by the spring-catch c, which engages with a groove around the head or end of the bobbin.

D is a plate placed upon aprojection of the shuttle-body immediately in front of the bobbin, and has secured upon its top the tensionregulating mechanism for the yarn. Upon the side, the outer end of which is bent upwardly, forming the tension-pin. 0?. Near the forward end of the plate isa pin, (1 which hasarightangled turn in its length, forming a hook, d around which the thread passes. In the side of the shuttle, and opposite the plate D, is cut a vertical slot,-e, over the top of which is placed a bridge, E.

Between the point e of the bridge and the slot the top of the shuttle is cut away sufficiently to allow the thread to pass along under the bridge into the slot, as shown.

In threading the shuttle the bobbinis placed in position on the spindle B, the end of the thread passed through the ring d to the righthand side of the pin (1 around the pin d back aroundthe pin d under the bridge E, and into the slot in the side of the shuttle-body, as shown. The disk d and pin 01 regulate the tension. If the disk is turned toward the pin d the tension will be lessened, and increased as it is turned toward the ring d.

What I claim is 1. The combination of the guide ring d and hooked pin d with the plate D, disk (1, and tension-pin 01 all arranged to operate substantially as shown and described.

2. The tension-regulating mechanism, consisting of the ring d, pivoted tension-disk at, having pin d hooked pin (1 and the plate D, all combined and arranged as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
